I think that if anyone is going to shoulder something, then it should be a rifle. I also think that if used for a backpack in the mountains up north in brown territory, then it will be useless because you won't have the time to stop a charging brown with that G20, so leave it at the hip where it belongs.
I would be using it at the range to have fun with and for my kids to have more points of contact. I think the idea of changing it up the feel with out buying another firearm
